  • Approved medicine71

    Approved as a medicine by the FDA or the EMA for at least one indication. Approval covers the named indication and formulation only.

  • In clinical trials19

    In human clinical trials and not yet approved by the FDA or the EMA. Results to date are from trial populations under medical supervision.

  • Research compound53

    Not approved as a medicine by the FDA or the EMA. Some are registered in individual countries. Supplied for laboratory research only.

  • Cosmetic ingredient17

    Used as a topical cosmetic ingredient. Cosmetic use is not a medicinal approval, and most evidence comes from manufacturer and small panel studies.
